Solution

The correct option is B $N a_{2} S_{4} O_{6}$
The reactions are shown below.
1) $N a_{2} C O_{3} + 2 S O_{2} + H_{2} O \to 2 N a H S O_{3} (A) + C O_{2}$
2) $2 N a H S O_{3} + N a_{2} C O_{3} \to 2 N a_{2} S O_{3} (B) + H_{2} O + C O_{2}$
3) $N a_{2} S O_{3} + S \to Δ N a_{2} S_{2} O_{3} (C)$
4) $2 N a_{2} S_{2} O_{3} (C) + I_{2} \to N a_{2} S_{4} O_{6} (D) + 2 N a I$
The product D is $N a_{2} S_{4} O_{6}$ .
